The U (1) × SO(4) covariant derivative produces an action where the SO(4) generators do not commute with the Dirac matrices because the generators themselves are constructed from those matrices. This yields additional interactions absent in SU(2) and SU(3) Yang Mills theories. The contributions from these interactions produce T-matrix elements consistent with the Newtonian and post Newtonian interactions found in the low energy limit of classical general relativity theory for both...

A previous paper ( http://vixra.org/abs/1111.0111 ) makes some calculations from a quantum gravity theory and sketches a framework for further predictions. This paper defends in detail the lagrangian for quantum gravity, based on the theory in our earlier paper, by examining the simple physical dynamics behind general relativity and gauge theory. Topics: Quantum gravity, general relativity
We have non-speculative, concrete evidence that dark energy is the mechanism of gravity, analogous to the U(1) spin-1 electrodynamics field equation, so the lagrangian for repulsion of masses has a similar propagator for repulsion of similar charges in QED (Moller scattering). Therefore, in the presently-observable (low energy) limit of quantum gravity (very small coupling), Feynman’s well-tested rules for calculating the perturbative expansion of the path integral show that: (a) only the...

In a previous paper the Ehrenfest Principle was used to explore a conceptual bridge between classical and quantum physics (Part I). In this paper several of the concepts outlined in Part 1 are further refined. Topics: Ehrenfest Principle, gravitation, Casimir Effect, quantum gravity
Maxwell's equations of electromagnetism describe three dimensional electric and magnetic field line divergence and curl (rank 1 tensors, or vector calculus), but were compressed by Einstein by including those rank-1 equations as components of rank 2 tensors. However, Einstein did not express the electromagnetic force in terms of a rank-2 spacetime curvature. In order to unify or even compare the equations for two forces (gravity and electromagnetism), you need first to have them expressed in...

The statistical mechanics described by partition functions for quantum gravity that assume a finite number of degrees of freedom for a fixed finite spacetime region are discussed. It is shown that a cosmological constant arises naturally as a Lagrange multiplier needed to fix the 4-volume in the canonical ensemble and that in the grand canonical ensemble, the cosmological constant naturally emerges in terms of a volume normalized chemical potential as Lambda = -8 pi mu. This result is... Topics: cosmological constant, quantum gravity, emergent spacetime
P. H. Frampton (author of Gauge Field Theory), in 2012 published a paper(1) noting that in observed flat spacetime the Friedmann-Robertson-Walker (FRW) metric of general relativity reduces to a simple Newtonian form, where a very simple repulsion term can be added for dark energy. Frampton postulated ad hoc outward acceleration due to dark energy: a = 2GM/R^2. We compare the predictions from Frampton's theory to more recent (March 2013) Planck space telescope cosmological parameters, which...

Feynmanâs relativistic path integral replaces the non-relativistic 1st quantization indeterminancy principle (required when using a classical Coulomb field in quantum mechanics) with a simple physical mechanism, multipath interference between small mechanical interactions. Each mechanical interaction is represented by a Feynman Moller scattering diagram (Fig. 1) for a gauge boson emitted by one charge to strike an effective interaction cross-section of the other charge, a cross-sectionl that...

The contribution of a scalar field to the graviton self-energy is determined to one-loop order in an emergent spacetime approach. It is shown that the self-energy makes a small correction to the bare propagator and that the self-energy has the form required by gauge invariance and Lorentz covariance.

An experimental and theoretical space warp drive Consider a rectangular box containing a movable mass that can be moved from one end of the box to the other and back again by the expenditure of energy. Is it possible to move the mass back and forward in the box with forces which are different in each direction, so that the box acquires a net thrust in one preferred direction? Force is the rate of change of momentum, F = dp/dt, so rearranging we find that momentum is the equal to the force...

It has previously been shown that models where Lorentzian spacetime is emergent from an underlying discrete Euclidean structure allow UV-finite gauge theories to be constructed that preserve local Lorentz covariance and it was argued that such models provide a viable approach to quantum gravity. Here black holes are considered in these emergent spacetime models. It is shown that it is possible to construct solutions to Einstein's equation for the black hole metric that include the vacuum stress...

It is shown that general relativity can be modified in a manifestly covariant way to alter the conformal mode sector. This modification can be selected to eliminate the conformal mode problem in Euclidean quantum gravity with or without modifying classical general relativity. Approaches to dark matter and/or dark energy that rely on a classical real scalar field can be re-interpreted as a conformal mode modified general relativity without any additional fields where the conformal mode plays the...

It is shown that UV-finite Lorentz covariant and gauge invariant quantum field theories can be constructed based on the premise that Lorentzian spacetime is emergent from a statistically averaged ensemble of discrete "pre-spacetimes" having Euclidean signature via a local Wick rotation. A continuum approximation to the underlying discrete theory is developed by expanding fields in terms of a finite number of eigenfunctions of an appropriate gauge covariant Laplacian. The resulting... Topics: quantum gravity, quantum field theory, emergent spacetime, UV-finite, gauge theory

So far, despite considerable e_ort, we�ve only discussed the free string. We now wish to consider interactions. If we take the analogy with quantum �eld theory as our guide, then we might be led to think that interactions require us to add various non-linear terms to the action. However, this isn�t the case. Any attempt to add extra non-linear terms for the string won�t be consistent with our precious gauge symmetries. Instead, rather remarkably, all the information about interacting...

Is it the dream of building grand intellectual edifices capable of describing the Universe with amazing accuracy and elegance? Or, perhaps, discovering something so unexpected that it totally blows your mind? Maybe it's simply the act of doing physics! Whatever the case, there are certainly many things in physics to get excited about, and we'll explore some of them in this class.

A non-Abelian, Universal SpaceTime Ontology is introduced in terms of categories, functors, natural transformations, Higher Dimensional Algebra and the Ontological Theory of Reality Levels. A paradigm shift towards non-commutative spacetime structures with remarkable asymmetries or broken symmetries, such as the CPT-symmetry violation, is proposed. This has the potential for novel applications of Higher Dimensional Algebra to spacetime structure determination in terms of universal, topological...
